A beautiful original set of six Pyrex JAJ (James A Jobling, England) small ramekins which would have been part of the Baking Set no 2186 from the early 1960s (designed in 1959).
The lovely custard cups/ramekins are made of moulded white milk/opal glass, coated with pastel colours on the outside. They're from the later version/colourway of duck egg blue, spring yellow and deep coral which was released in 1961, so circa 1961-1962 vintage. The bases have just the crown logo. 
Multi purpose - perfect for both baking small desserts such as individual crumbles, souffles, etc. or for serving custard, ice cream, sweets, nibbles.
Very nice clean examples with no chips - the colours are good with not much loss of coating. One yellow cup has some scratches, see pics. Each one is 5.7cm tall x 8.7cm wide. 
The photos make them look more blue - the bluey coloured pot is duck egg (pale blue green) rather than darker turquoise.
Includes P&P to the UK.
